I had no trouble with the previous upgrade, so perhaps was a bit confident with this one! I followed the directions for 1.1, but seem to have broken the themes, getting the following error on any public page (the back-end still works):
Catchable fatal error: Argument 1 passed to Zend_Controller_Front::registerPlugin() must be an instance of Zend_Controller_Plugin_Abstract, instance of Omeka_Core given, called in /home/.backyards/(USERNAME)/(WEBSITENAME)/omeka/index.php on line 22 and defined in /home/.backyards/(USERNAME)/(WEBSITENAME)/omeka/application/libraries/Zend/Controller/Front.php on line 719
The caps/brackets are my edits.
Any ideas? What do I need to fix?
